CHIMNEY-COWL.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed May 23,1907. Serial No. 275,347.

To all whom it may concern.-

Be it known that I, AMos H. HOLTZINGER, a citizen of the United States,residing at Bedford City, in the county of Bedford and State ofVirginia, have invented new and useful Improvements in Chimney-Oowls, ofwhich the following is a specification.

This invention relates to improvements in chimney cowls, comprehendingthe provision of a simple and effective device of this character adaptedto be securely mounted in position. upon the chimney and including a boxformed of a base section and a hood carrying section, the latter beingdesigned for readyremoval and convenient reapplication, as occasion mayrequire in cleaning the chimney, making repairs and other similaroperations.

The invention consists of the features of construction and combinationof parts, hereinafter fully described and claimed, and is illustrated inthe accompanying drawing, in which:

Figure 1 is a perspective view. illustrating the application of the cowlto a chimney. Fig. 2 is a side elevation of the cowl detached: Fig. 3 isa cross section thereof on the line of the spring catches. Fig.- 4 is aside elevation of the base section.

Referring to the drawing, 1 represents a conventional form of brickchimney, and 2 the improved cowl applied thereto.

The cowl comprises a box or chambered body comprising a base section 3and a hood-carrying section 4, said box or body being perferably ofoblong rectangular form to correspond substantially to the shape of thechimney flue. The base section 3 is preferably, like the hood-carryingsection 4, formed of sheet metal and is provided at its lower end withan anchoring flange or projection 5 extending around the same, and abovesaid flange is formed with an external bead or shoulder 6. Said section3 occupies the upper portion of the flue opening in the chimney 1 withits bead or shoulder 6 resting upon the upper surface of the upper tieror course of bricks 7 and closing the joint between the same and box,while the flange 5 underlies the course 7 and is arranged between thesame and the course of bricks below, being thereby bound or held inposition by the upper course. The bricks are cemented or otherwise boundin the usual way, thereby firmly and permanently fastening the basesection 3 in position to prevent any possibility of the cowl beingdisplaced by wind pressure or otherwise rendered unserviceable in use.The cowl-carrying section 4 is adapted to slip down or telescope overthe upper portion of the section 3 and to rest against the upper surfaceof the bead or shoulder 6, and said section 4 is provided at oppositesides withspring latches 8 projecting inwardly through openings thereinand adapted to snap into corresponding keeper openings 9 in the section3, thus securely and detachably fastening the section 4 in position. Thetop of the section 4 has the upper edges of its side Walls beveled andits end walls provided with concaved recesses to receive the tubularhood 10 which seats therein and is riveted or otherwise fastenedthereto, solder or other means being preferably employed to close thejoints. The hood 10 extends longitudinally of the box and projectsbeyond the end of the same, its ends being beveled or inclineddownwardly, as indicated at 11, to secure an effective draft.

It will be seen from the foregoing description that the base section ofthe device may be firmly and permanently fastened in position upon thechimney, while the top or hood-carrying section may be applied andremoved at will, thus enabling it to be conveniently detached, when itis necessary to repair or clean the chimney or when the substitution ofa new hoodcarrying section is necessary, and as readily and convenientlyplaced in position. That portion of the base of the hood which isconfined within the boundary of the box is provided with an opening 12communicating with the box for the discharge of the products ofcombustion.

Having thus described the invention, what is claimed as new, is:

1. A chimney cowl in the form of an oblong rectangular box comprising abase section, a cowl-carrying section telescopically engaging the 'basesection, projections upon said base section to extend over and beneaththe top course of bricks of a chimney, the upper projection forming asupport and stop to limit the downward movement of the cowl-carryingsection, fastening means for detachably connecting said sections, and anelongated tubular hood or cowl mounted upon said cowl-carrying section.

2. A chimney cowl in the form of an oblong rectangular box comprising abase section provided with a sur rounding basal flange to extend beneaththe top course of bricks of a chimney, and a shoulder above said flangeto rest upon the upper surface of the bricks, and a hood orcowl-carrying section detachably mounted upon the up wardly projectingportion of said base section and resting upon and limited in downwardmovement by said flange.

3. A chimney cowl in the form of an oblong rectangular box comprising abase section having an external basal anchoring flange extending aroundthe same, and an external shoulder arranged above said flange, a topsection telescopically engaging said base section and adapted to restupon the flange, means for detachably connecting said sections, and acowl comprising a tube horizontally mounted upon the top section.

In testimony whereof, I afiix my signature in presence of two witnesses.
